litecoin is practically in a few words a lighter and more powerful version than bitcoin. It was created in fact to try to solve some flaws present in bitcoin, and to date it has been a total success. It was created not to compete with bitcoin, but to be an alternative focused on more efficient payments and cheaper commissions.
Litecoin is also known for having a greater scalability not only than bitcoin but also bitcoin and ethereum at the same time. the speed when making transactions with litecoin is one of its greatest advantages, since it needs a single confirmation of about 2.5 minutes compared to the 10 minutes it would take for bitcoin.
It presents an issue of coins 4 times greater than bitcoin, something that will undoubtedly cause its value to increase in the future when there is no more bitcoin to mine. I have personally been doing all my transactions with litecoin lately since the value of the commissions is minimal and the speed with which they are carried out is another point in favor.
